WILLIAM P1 DAVIES, OF CINCINNATI, OHIO.

WHEEL To all whom it may concern:

Be it known that l, VViLLiAM P. DAvnis, of Cincinnati, in the county ofHamilton and State of Ohio, have invented certain new and usefulImprovements in Wheels; and do hereby declare the following to be afull, clear, and exact description of the invention7 such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in wheels and more particularlyto such as employ elastic tires,-the object of the invention being to soconstruct the wheel that its tire portion shall be elastic and avoiddanger of puncture and which may embody as a portion of its structureone or more cushions.

A further object is to so construct the tire portion of a wheel that thecombined elas" ticity of a spring and elastic tubing or cushion can beutilized.

l/Vith these objects in view the invention consists in certain novelfeatures of construction and combinations of parts as hereinafter setforth and pointed out in the claims.

1n the accompanying drawing, Figure 1 is a face View (partly brokenaway) of a Wheel embodying' my improvements. Fig. 2 is a partialtransverse sectional view. Fig. 3 is a face view of a wheel embodyingcertain modiiications. Fig'. t is a transverse sectional view of thewheel shown in Fig. 3, and Fig. 5 is a peripheral view of the hub 22.

1 represents the body portion of the wheel and 2 the tire portion. Thebody portion 1 comprises a hub 3 having a tapering interior, withinwhich a series of rings aredisposed which constitute a bushing againstwhich anti-friction rollers 5 have a bearing. A.

shaft or axle G projects through the bushing within the series ofanti-friction rollers, and is provided at its free end with a nut 7 bymeans of which the ring-bushing can be moved longitudinally within thehub and compensate for wear. The end of the shaft or axle and the nutthereon are protected by means of a cap 8 secured to the hub. The hub 3is provided with a series of sockets 9 for the reception of spokes 10and to the outer ends of these spokes a felly 11 is secured.

The tire portion of the wheel comprises a plate of spring metal 12, bentto form a series of annular corrugations 13. A shoe 14C encircles thecorrugated spring plate 12 and Specification of Letters Patent.

retains in place a suitable tread portion 15. In order that this springtire shall be permitted to yield where pressure is applied withoutunduly displacing other portions of the tire, the corrugated springplate 12 is split radially at a number of places, as indicated by thelines 16 on Fig. 1. Between the corrugations of the spring tire, rubbercushions 17 are located.

To each side of the felly 11 a plate 18 is securely bolted. These platesembrace the spring tire and serve to prevent displacement of the rubbercushions interposed be'- tween the convolutions of the spring, and also,to strengthen or support the said spring tire laterally.

Instead of constructing the body portion of the wheel with spokes, thesaid body-por tion may comprise a single corrugated plate 19, as shownin Figs. 3, t and 5. That portion of the corrugated plate 19 in closeproximity to the periphery thereof is made plain and has secured theretothe depending portion 2O of the inner convolution of the spring tire.rlhe latter is also supported on the plate 19 by means of `a flangedring 21 secured thereto. In the construction shown in Figs. et and 5 thehub 22 of the wheel is provided with a peripheral serpentine flange 23which forms seats for the recep `-ion of the corrugated body portion 19of the wheel and said hub and body portion are secured together by meansof bolts 211.

In Fig. 4t I have illustrated a series of cushions 25 in the form oftubes, and if desired several such tubes may be disposed in eachcorrugation of the spring.

Other slight changes might be made in the details ofconstruction of myinvention without departing from the spirit thereof or limiting itsscope and hence I do not wish to restrict myself to the precise detailsherein set forth.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is

1. A wheel provided with a tire portion comprising a spring plate bentto form a series of annular corrugations superimposed radially andcushions interposed between said corrugations.

2. A. wheel provided with a tire portion comprising a spring plate bentto form a series of annular corrugations, cushions interposed betweensaid corrugations, and

series of annular oorrugations and seated on said felly cushionsinterposed between the oorrugations of said spring plate, and platessecured tothe felly and embracing the Corrugated spring plate andinterposed enshlons.

In testimony whereof, I have signed this 20 specification in thepresence of two subscribing witnesses.
